ELECTRICAL COIL

摘要

The present invention relates to an electrical coil which includes a wire rod, an insulation member, and an installation member made of a plastic material, wherein especially the wire rod composing the electrical coil is composed by being coated with enamel and spirally wound with a certain frequency. The wire rod composing the electrical coil is composed of the wire rod made of an aluminum material coated with the enamel. A copper wire rod is wired on both ends of the aluminum wire rod respectively. The electrical coil used in an electric motor is composed of the wire rod made of the aluminum material and simultaneously a condition value is satisfied, thereby solving a cost problem caused by using an existing copper material and a corrosion problem and a disconnection problem caused by using the aluminum material at a single stroke.
